Check engine

The 'Check Engine' light on our Linea came ON the other day . The service center guys had no clue , and after a lot of hit and trial the issue was solved when they drained some engine oil . The problem has started again . Could anyone tell me the reason for this . The blue and me system also stopped working some time back , for which they were demanding over Rs.12000 . Also suggest some service centers in Delhi if you could .

May be if you could provide some more information like year of purchase, dealer etc people will be able to help in better way.
Why not try disconnecting the terminal and again connecting it. This may work. may be a corrupted software problem. Are you feeling any change in performance?

Today i got Check Engine in the display and can see light being grown all the time. Called service guy on the spot was told to me no issues can drive the car with no issues. I drove back home and parked my car and will be taking my car to service station tom. I feel turbo is also lacking while driving after 2000 rpm. Please advice what should I do.

Good news...!!! got the "check engine" light error diagnosis and the problem was with one of the hose pipe which was loose. now my beauty is back with the same pickup and turbo power... Njoying driving again...;-)
